It was way back in early May that the kernel source for Sprint and US Cellular Galaxy S4 variants showed up on Samsung's servers. The Virgin Mobile Canada edition was added in April. The Verizon and AT&T devices came in the following weeks, but no peep from the T-Mobile version. Well, until today – Samsung just posted the T-Mobile GS4 kernel source in all its glory.

At today's Samsung Premiere 2013 event in London, the Korean smartphone giant announced that it will begin selling the Galaxy S4 in five additional colors. These new models won't be different internally from what's currently available, just more eye-catching. It remains to be seen if this colorful strategy will give a boost to the Galaxy S4's sales numbers, not that it needs all that much help. The Galaxy S4 is still outselling all other Android smartphones by a wide margin, even if it isn't doing so quite as spectacularly as investors would want.

Two days ago, we reported on the rumored existence of a new Galaxy S4 iteration with LTE-Advanced support headed to Korea. It seems that device has been all but confirmed today, thanks to a leaked user manual with device specifications found by Japanese blog rbmen.

The device, known as model number SHV-E330, contains an MSM8974 CPU, which will be the first Qualcomm Snapdragon 800 SoC to debut in handsets later this year.

Most Android phones have big batteries these days, but that doesn't mean they always have enough juice for today's go-go smartphone user. Luckily, ZeroLemon has just started selling gigantic batteries for the Samsung Galaxy S4 and LG Optimus G Pro. Sometimes form has to take a backseat to function.

A great cheer rose up from the internet early this month when Samsung added listings for the Qi wireless charging accessories compatible with the Galaxy S4. The cheer then quickly faded into a confused murmur as everyone realized you couldn't actually order them. The accessories have been listed as backordered ever since. At last, the white replacement back and the Samsung-branded Qi charger have shown up as in stock.

We knew Samsung's latest entry to the Galaxy Note series was getting an AT&T LTE version, and today the carrier has released more detailed information about its launch. Those of you that want to take your notation on the go can pick up a Galaxy Note 8.0 On June 21st (this Friday) for $399.99, with a two-year contract. That's pretty pricey, especially after other carriers have moved towards no-contract pricing for tablets - it's just as expensive as the commitment-free WiFi version.

The Samsung Galaxy S4 might be a new phone, but there are already some great deals to be had online. Amazon previously lowered the price to $168, but now it's down to just $129.99 for new lines, and $139.99 for upgrades on existing ones.

It's fun to joke about Samsung's phones feeling cheap because they're made of slippery plastic, but that doesn't mean they're actually cheap. Samsung just posted a video tour of the lab where the Galaxy S4 is tested for reliability, but let's call it what it is – this is Samsung's smartphone torture chamber. The video is in Korean, but you can turn on English closed captioning.

The Galaxy S4 takes everything from drops to impacts and comes out fully functional.

Developers take note: Samsung is getting some more source code out the door, but it's just one device this time. The kernel source for AT&T's version of the Galaxy S4 is out, and it's up for grabs at Samsung's open source site.

Kernel source for a few other variants of Samsung's flagship have already been posted. In fact, this development means T-Mobile is the only major carrier whose GS4 hasn't joined the open source club.

A few days ago, Dell dropped the price of both Sprint's and Verizon's variants of the Galaxy S 4 to $119 and $129 respectively. Not to be outdone, Amazon Wireless has now undercut Big D by $10, and is offering Verizon's GS4 for $119 for new contracts ($170 for upgrades). That's a pretty solid deal if you don't want to buy from Dell, though I'd be remiss not to mention the $50 eGift card that Dell is throwing in if you do decide to buy through them.
